Definition and Usage
The <datalist> tag specifies a list of pre-defined options for an <input> element.The <datalist> tag is used to provide an "autocomplete" feature on <input> elements. Users will see a drop-down list of pre-defined options as they input data. The HTML<datalist> element contains a set of <option> elements that represent the values available for other controls. For example, if a user began entering some text into a text field, a list would drop down with prefilled values that they could choose from.
Usage
The<datalist> tag can be used in conjunction with an <input> element that contains a list attribute.
The list attribute is linked to the <datalist> tag by the <datalist> tag's ID. For example, if the <datalist> tag contains id="myData", then the list attribute will look like this: list="myData".
You can fill the <datalist> element by nesting <option> tags inside the <datalist> tag.
